Japan's own Green House Co. today introduced the PicoDrive Secure, a new line of flash drives which help keep your data safe from prying eyes by utilizing hardware-based AES 256bit encryption.
The PicoDrive Secure units measure 65 (W) x 19 (D) x 8 (H) mm, they weight 11 grams, have an USB 2.0 interface, provide a password lock function, and allow users to set them as 'read-only' (temporary of course) so no other data (that may contain malware) can be transferred.
Green House's encryption-enhanced drives are available in 2GB ($160), 4GB ($230), 8GB ($300) and 16GB ($355) capacities.
